Background: Huntington's disease (HD) patients often present with abnormal modulation of blood pressure and heart rate. We investigated whether cardiac autonomic innervation assessed by 123I-metaiodobenzylguanidine (MIBG) imaging is impaired in HD patients, in comparison with controls (Ctrl).
Methods: Fifteen patients (6 F and 9 M) were assessed by the motor section of the Unified HD Rating Scale, the Total Function Capacity, and the scale for outcomes in Parkinson's disease-autonomic (SCOPA-AUT) questionnaire.
Objective: In visuo-constructional tasks, patients may reproduce drawings near-to or superimposed on a model, showing the so-called "Closing-in" (CI), often ascribed to a defect in inhibitory control. CI has been described in neurological conditions, but no studies have explored CI in Huntington's disease (HD), a neurodegenerative disorder often involving the frontal cortical-subcortical circuits. We searched for the occurrence of CI in HD patients and systematically investigated its correlates to find a clinical marker of the frontal/executive dysfunctions in the early examination of HD patients.

Particularly, low HtrA1 mRNA levels have been observed in breast cancer patients with more aggressive clinical features. These have been shown to relate to a longer disease free and overall survival, with more pronounced effects in axillary nodes positive patients.

There is increasing evidence pointing towards an involvement of the endocrine system in HD. Recent studies, investigating the increased risk of diabetes mellitus and impaired insulin sensitivity and secretion in HD patients, led to contradictory results.

Methods: All medical records of HD patients followed between 1977 and 2008 at the Department of Neurological Sciences of Federico II University in Naples were retrospectively reviewed and 135 patients were enrolled in the analysis. At the time of data collection, 41 patients were deceased (19 males and 22 females) with a mean ± SD age at death of 56.
A retrospective study of 502 patients treated with tunable flashlamp pulsed dye laser for superficial vascular malformations (433), ulcerated hemangiomas (65) and postinvolutional redness (4) is presented. Patients were treated in the period from June 1997 to March 2006, with follow-up ranging from six months to four years. The age of the patients ranged from three months to 80 years.

Several studies have demonstrated that hypothalamic dysfunction is part of the phenotypic spectrum. The aim of the study was to evaluate the growth hormone (GH) response to arginine infusion in a cohort of HD patients, to search for an in vivo biomarker of hypothalamic dysfunction.

Clinical heterogeneity has been reported and thyroid and respiratory abnormalities may be present. We describe 3 patients of an Italian family carrying the S145X mutation in the TITF-1 gene with mild motor delay, childhood onset dyskinesias, and subtle cognitive impairment.

His mother and his grandfather were affected by hypothyroidism with a late onset and benign hereditary chorea. The aim of this study was to establish the genetic defects that cause that phenotype and study the molecular mechanisms of the pathology.

Nine patients with a molecular diagnosis of HD were screened for response to acute apomorphine injection. Four of them, not ameliorating at the acute test, were discontinued.
